IRRIGATION SYSTEM.

Application filed May 21, 19 20.

T wZZ whom it may concern Be it known that, I, WALTER KRAUsn, a citizen of Germany, and resident of Friesack, Mark, Germany, have invented certain a new and useful Improvements in Irrigation Systems, for which I have filed applications in Germany, March 4, 1918, patent not yet issued; Austria, January 29, 1919, Patent 1 0. 85,056, issued August 10, 1921; Hun- 1o gary, February 1, 1919, patent not yet issued; France, February 11, 1919, Patent No. 517,861, issued December 22, 1920; Spain, February 22, 1919, Patent No. 69,124, issued August 28, 1920; Denmark, February 4, 1919, 16 Patent No. 26,536, issued August 18, 1920;

February 25, 1919, Patent No. 542/99; to Sweden, January 31, 1919, patent not yet issued; Luxemburg, October 29, 1919, Pat ent No. 11,541, issued October 29,1919; Canada, May 26, 1920, patent not yet issued; Finland, October 30, 1919, Patent No. 8,114, issued August 13, 1920; Great Britain, January 27, 1920, Patent No. 138,345, and of which the following is a specification.

My invention relates to improvements in irrigation systems. More particularly my invention relates to systems of that type in which the water is supplied from a. main supply conduit to a field conduit adapted successively to be connected to different outlets of the supply conduit, and from the field conduit to a sprinklinrgconduit adapted suc cessively to beconnected to different outlets of the field conduit. The object of the improvements is to provide a system of this class and a method of operating the same in which the loss of time caused by shifting the field and sprinkling conduits from one point of use to another is reduced. VViththis and other objects in view my invention consists in the matters to be described hereinafter and particularly pointed out in the appended claims. For the purpose of describing the invention an example embodying the same has been shown in the accompanying drawing, in which the same letters of reference 50 have been used in all the views to indicate corresponding parts, In said drawing,

Fig. 1, is a diagrammatioal plan vlew illustrating my improved system,

Fig. 2, is a detail view showing one of the sections of the field conduit, and

Serial No. 383,326.

Fig. 8, is: a vertical cross-section taken '0 the line A-A of Fig. 2.

As shown in Fig. 1, the system consistsv of a main supply conduit T having a plurality o normally closed outlets 't, 25 etc,, a field conduit F constructed in sections F F ,F F and adapted to be successively connected to the outlets t, 6 of the main conduit, and a sprinkling conduit R adapted to be successively connected to different outlets of the field conduit. In the operation ot the system the sprinkling conduit'R is alternately moved away from. the mainconduit and towards the same, as is indicated by thearrows B, B B and when it arrives at the outlet of the field'conduit which is next to the main conduit the field conduit is closed as against the main conduit, where upon the field conduit and the sprinkling conduit are taken apart and moved to the neXt'outlet of the main conduit. This operation takes much time which is lost for the sprinkling operation, the length of the field conduit being as much as1500 feet, and the distance between successive cutlets t of the main conduit being as much as 1200 feet. In order to reduce the loss of time .1 provide the field conduit with valves S S S etc., and when moving the sprinkling conduit towards the main conduit I close the sections of the field conduit located behind the sprinkling conduit, and I dismount the said sections and transport thesame to the points of the next operation while sprinkling is continued. Therefore, when the sprinkling conduit is connected to the valved outlet C of the section F which is next to the main conduit T most of the sections of the field conduit have already been carried to the position V indicated in dotted lines and, assembled in such position, so that only the last section F of the field conduit and the sprinkling conduit it require tobe carried into the position V and connected to the outlet from the main conduit and the section F of the field conduit while the sprinkling operation is interrupted.

In order that the water left within the closed sections of the field conduit may not flow out at one part of the field, which would excessively moisten the soil and actually result in a waste of the water, I prefer to provide means for withdrawing the water from the said sections of the field conduit prior to dismounting the same. In Figs.

2 and 3 I have shown preferred means to withdraw the water. As shown in the said teatime eiid ofthe section F a slide valve S two branch pipes 2 and 3, and an air cock a are located. The branch pipe 2 is connected t'o'lthe bottomi'part of the section F and at the rear of the slide valve S as seen from the main eonduit,

and it surrounds the pipe 3 which is connected to a suitable part of the section "F and in front of the valve, S said pipe :3 b eirig iii theforfnbf anoint. The cock 4. is provided at theupper; part'of the sectidnfj jjj'and at the rear of the valve S Now, if-the valve S is closed and the cock 4' openedwhile the section F is under pressure, "the water left within the section F atj the rear of valve S and within the sec tionfF 'is withdrawn throughthe pipe .2, the nozzle 3 acting as an ejector, and the said water can, either directly be sprinkled bylsuitable means provided on the free end of the pipe 2, or be supplied'to' the sprinkliiig'co'nduit.

As in'som e cases the section F may be inclined I" prefer to provide a-second air (500125. at the opposite end of the section F [Itwill be understood thatinstead of the suction {apparatus shown in the figures other suitable: means may be provided for distributing thewater from the sectionsover the field.
